A state of being, that is defined as one being, "Grundy". An adjective denoting a person, person's actions, or state of being distinguished as anything gnarly, without the positive attributes. Grubby, sludgy, smelly, rotten, vile, dishonest or scheming. Shenanigans, outlandish tom foolery and definitely not cool or admirable. In the hood, this can be known as "greezy".
